QUESTION: 
I would like to know what rocket fuel is made of?  

ANSWER from Cathy Davis on December 17, 1996:
There are two main types of rocket fuel, liquid and solid fuel. 
Liquid fuel can be of several kinds like liquid oxygen and liquid hydrogen, 
liquid oxygen and kerosene, or hydrazine and nitogen tetroxide, plus others. 
Solid fuel is a composite mixture of usually ammonium perchlorate and 
aluminum, or sometimes simple black powder.
